I just went thru the same issue last week- center head bolt broke off in block. I did not want to heat for fear of creating hot spots in cyl wall near bolt. I soaked w/pen. oil and gave it a couple hits twice a day for a week and welded a nut to it the next weekend. Took some working back and forth until the bolt started to move in the hole but after a couple turns I was out of the woods without heating the block.
